TECHNICAL FIELD

The present disclosure generally relates to imaging technology, and inparticular, to systems and methods for image storage.

BACKGROUND

With the development of medical science and technology, medical imagingbecomes more and more important. A scanning device (e.g., a magneticresonance (MR) device, a computed tomography (CT) imaging device, anX-ray imaging device, an ultrasound device, a positron emissiontomography (PET) device, a digital radiography (DR) device) can be usedto perform scanning on a subject and determine scanning images based onscanning results. The scanning images can be used to analyze internalcondition of the subject. In current practice, the scanning images maypresent the internal condition of the subject. However, scan statusinformation of the subject during scanning cannot be traced back when auser is viewing the scanning images. In some cases, it may be beneficialfor the user to understand the status information of the subject duringscanning. Therefore, it is desirable to provide systems and methods forstoring the scanning images and other images (e.g., optical images) ofthe subject that include the scan status information of the subjectduring scanning, such that the user can trace back to the scan statusinformation of the subject when viewing the scanning images, therebyimproving efficiency and/or accuracy in analyzing the scanning images.

FIG. 1 is a schematic diagram illustrating an exemplary image storagesystem according to some embodiments of the present disclosure. Asillustrated, the image storage system 100 may include an imaging device110, a network 120, a terminal device 130, a processing device 140, anda storage device 150. The components of the image storage system 100 maybe connected in one or more of various ways. For example, the imagingdevice 110 may be connected to the processing device 140 through thenetwork 120. As another example, the imaging device 110 may be connectedto the processing device 140 directly (as indicated by thebi-directional arrow in dotted lines linking the imaging device 110 andthe processing device 140). As a further example, the storage device 150may be connected to the processing device 140 directly or through thenetwork 120. As still a further example, the terminal device 130 may beconnected to the processing device 140 directly (as indicated by thebi-directional arrow in dotted lines linking the terminal device 130 andthe processing device 140) or through the network 120.

The imaging device 110 may include a scanning device 111 and a capturedevice 112 (e.g., a piece of photographic equipment, a piece of thermalimaging equipment, etc.). The scanning device 111 may scan an objectlocated within its detection region and generate scanning imagesrelating to the object. In some embodiments, the object may include apatient, a man-made object, etc. In some embodiments, the object mayinclude a specific portion, organ, and/or tissue of a patient. Forexample, the object may include a head, a brain, a neck, a body, ashoulder, an arm, a thorax, a cardiac, a stomach, a blood vessel, a softtissue, a knee, feet, or the like, or any combination thereof. In thepresent disclosure, “subject” and “object” are used interchangeably. Insome embodiments, the scanning device 111 may include an MR scanningdevice, a CT scanning device, an X-ray scanning device, an ultrasoundscanning device, a PET scanning device, a DR scanning device, or thelike, or any combination thereof. Merely by way of example, the MRscanning device may include a main magnet assembly for providing astrong uniform main magnetic field to align the individual magneticmoments of H atoms within the object. During this process, the H atomsmay oscillate around their magnetic poles at their characteristic Larmorfrequency. If the object is subjected to an additional magnetic field,which is tuned to the Larmor frequency, the H atoms may absorbadditional energy, which rotates the net aligned moment of the H atoms.The additional magnetic field may be provided by an RF excitation signal(e.g., RF signal generated by RF coils). When the additional magneticfield is removed, the magnetic moments of the H atoms may rotate backinto alignment with the main magnetic field thereby emitting an MRsignal. The MR signal may be received and processed (e.g., by Fouriertransform (FT) of data in a k-space, frequency encoding, phase encoding)to form an MR image. As another example, the CT scanning device maygenerally include an X-ray tube that emits ionizing radiation thattraverses an examination region and a portion of an object therein andilluminates a detector array disposed across the examination region,opposite to the x-ray tube. The detector may produce projection dataindicative of the detected radiation, which may be reconstructed togenerate volumetric image data indicative of the portion of the object.With spectral CT, the projection data may include signals which areacquired concurrently and that correspond to different photon energyranges. There are several approaches for performing spectral CT. Forexample, the CT scanning device may include two or more sources, atleast one source of which is configured to switch between at least twodifferent kVps, and/or a detector array with energy-resolving detectors.As a further example, the X-ray scanning device may be configured toscan an object (e.g., a patient) using X-rays and generate image dataassociated with the object. The X-ray scanning device may include ascanning source, a table, a detector, or the like. The scanning sourcemay emit X-rays to scan the object or a portion thereof located on thetable. The detector may detect one or more X-rays emitted from thescanning source or scattered by the subject or a portion thereof toobtain projection values. The projection values may be transmittedand/or processed for generating a projection image.

The capture device 112 may collect one or more images (the “image”herein may refer to a single image or a frame of a video (also referredto as a video frame)) and/or a video related to the object. In someembodiments, the capture device 112 may include a camera, a videorecorder, a sensor, or the like, or any combination thereof. The cameramay include a gun camera, a dome camera, an integrated camera, amonocular camera, a binocular camera, a multi-view camera, or the like,or any combination thereof. The video recorder may include a PC DigitalVideo Recorder (DVR), an embedded DVR, or the like, or any combinationthereof. The sensor may include an acceleration sensor (e.g., apiezoelectric sensor), a velocity sensor (e.g., a Hall sensor), adistance sensor (e.g., a radar, an infrared sensor), a steering anglesensor (e.g., a tilt sensor), a traction-related sensor (e.g., a forcesensor), an image sensor (e.g., a visible sensor), or the like, or anycombination thereof. The image acquired by the capture device 112 mayinclude a two-dimensional image, a three-dimensional image, etc. In someembodiments, the image acquired by the capture device 112 may include anoptical image. In some embodiments, the capture device 112 may acquirethe image simultaneously with the scanning image. In some embodiments,the capture device 112 may transmit the acquired image to one or morecomponents (e.g., the terminal device 130, the processing device 140,and the storage device 150) of the image storage system 100 via thenetwork 120. In some embodiments, the capture device 112 may beintegrated into the scanning device 111 (e.g., at a position closed to aradiation source of the scanning device 111) and configured as acomponent thereof. In some embodiments, the scanning device 111 and thecapture device 112 may be configured as two independent devices.

In some embodiments, the scanning device 111 may work in coordinationwith the capture device 112 for acquiring a first image (e.g., ascanning image) and a second image (e.g., an optical image)simultaneously. For example, the scanning device 111 and the capturedevice 112 may be configured as two independent devices. A controldevice may be coupled to (e.g., connected to) the scanning device 111and the capture device 112, and may be configured to control workingtiming (or working sequence) of the scanning device 111 and the capturedevice 112, respectively. As another example, when the scanning device111 performs a scanning process on a subject for acquiring a firstimage, a trigger signal may be generated and sent from the scanningdevice 111 to the capture device 112 to cause the capture device 112 toacquire a second image simultaneously. As a further example, the capturedevice 112 may be integrated into the scanning device 111 and configuredas a component thereof. When the scanning device 111 performs a scanningprocess on a subject for acquiring a first image, a control deviceassociated with the scanning device 111 may control working timing ofthe capture device 112. In such cases, the scanning device 111 and thecapture device 112 may work simultaneously for acquiring the first imageand the second image, and accordingly, the second image may be acquiredduring scanning of the subject, and the second image may include scanstatus information of the subject. The scan status information may beassociated with a status of the subject when the first image isacquired.

However, it should be noted that the computingdevice 200 in the present disclosure may also include multipleprocessors, and thus operations of a method that are performed by oneprocessor as described in the present disclosure may also be jointly orseparately performed by the multiple processors. For example, if in thepresent disclosure the processor of the computing device 200 executesboth operations A and B, it should be understood that operations A and Bmay also be performed by two different processors jointly or separatelyin the computing device 200 (e.g., a first processor executes operationA and a second processor executes operation B, or the first and secondprocessors jointly execute operations A and B).

The storage 220 may store data/information obtained from the imagingdevice 110, the terminal device 130, the storage device 150, or anyother component of the image storage system 100. For example, thestorage 220 may store a second image (e.g., an optical image) and/orscan status information of a subject correspondingly with a first image(e.g., a scanning image) of the subject. In some embodiments, thestorage 220 may include a mass storage device, a removable storagedevice, a volatile read-and-write memory, a read-only memory (ROM), orthe like, or any combination thereof.

The data related to the object mayinclude identification information (e.g., a name, an age, a gender, aheight, a weight, a medical history, contract information, a physicalexamination result). The user may also input parameters needed for theoperation of the imaging device 110, such as image contrast and/orratio, a region of interest (ROI), slice thickness, an imaging type, ascan type, a sampling type, or the like, or any combination thereof. TheI/O 230 may also display images obtained from the imaging device 110,the storage device 150, and/or the storage 220. For example, a user(e.g., an operator) may input a request for viewing a first image (e.g.,a scanning image) stored in the storage device 150 via the I/O 230(e.g., an input device). The processing device 140 may output the firstimage and/or a second image (e.g., an optical image) for display basedon the request. The first image and/or the second image may be displayedvia the I/O 230 (e.g., an output device).

The communication port 240 may be connected to a network (e.g., thenetwork 120) to facilitate data communications.

FIG. 4 is a flowchart illustrating an exemplary process for imagestorage according to some embodiments of the present disclosure. In someembodiments, the process 400 may be implemented by an image storagesystem (e.g., the image storage system 100). In some embodiments, theimage storage system may be implemented by software and/or hardware,and/or may be integrated in an image storage device. In someembodiments, at least part of process 400 may be performed by theprocessing device 140 (implemented in, for example, the computing device200 shown in FIG. 2 ). For example, the process 400 may be stored in astorage device (e.g., the storage device 150, the storage 220, thestorage 390) in the form of instructions (e.g., an application), andinvoked and/or executed by the processing device 140 (e.g., theprocessor 210 illustrated in FIG. 2 , the CPU 340 illustrated in FIG. 3, one or more modules or units illustrated in FIG. 8 ). The operationsof the illustrated process presented below are intended to beillustrative. In some embodiments, the process 400 may be accomplishedwith one or more additional operations not described, and/or without oneor more of the operations discussed. Additionally, the order in whichthe operations of the process 400 as illustrated in FIG. 4 and describedbelow is not intended to be limiting.

In 410, a scanning image (also referred to as “first image”) of a targetscan object (also referred to as “subject”) may be obtained, and/or anoptical image (also referred to as “second image”) of the target scanobject may be obtained. In some embodiments, the processing device 140(e.g., the obtaining module 810 illustrated in FIG. 8 ) may preformoperation 410. In some embodiments, the scanning image may be acquiredby a scanning device (e.g., the scanning device 111). In someembodiments, the optical image may be acquired by a capture device(e.g., the capture device 112). The capture device may include a pieceof photographic equipment. In some embodiments, the optical image may beacquired during scanning of the target scan object.

As used herein, the target scan object may include a patient, a man-madeobject, etc. In some embodiments, the target scan object may include aspecific portion, organ, and/or tissue of a patient. For example, thetarget scan object may include a head, a brain, a neck, a body, ashoulder, an arm, a thorax, a cardiac, a stomach, a blood vessel, a softtissue, a knee, feet, or the like, or any combination thereof. In someembodiments, the scanning image may include or refer to a medical imageacquired based on an interaction between the target scan object (e.g., ahuman body) and a medium provided by a medical imaging device (alsoreferred to as “scanning device”, e.g., the scanning device 111illustrated in FIG. 1 ). The scanning image may be used to expressinternal information (e.g., a structure and/or a density of internaltissues and organs of the human body) of the target scan object.Exemplary mediums may include an X-ray, an electromagnetic field, anultrasonic wave, or the like, or any combination thereof. Exemplarymedical imaging devices may include an MR scanning device, a CT scanningdevice, an X-ray scanning device, an ultrasound scanning device, a PETscanning device, a DR scanning device, or the like, or any combinationthereof. In some embodiments, the scanning image may be atwo-dimensional (2D) image, a three-dimensional (3D) image, etc. In someembodiments, the scanning image may be obtained from a storage device(e.g., the storage device 150) disclosed elsewhere in the presentdisclosure. In some embodiments, the scanning image may be obtained fromthe medical imaging device directly.

In some embodiments, the optical image may be acquired using a piece ofphotographic equipment. Exemplary photographic equipment may include acamera, a video recorder, a sensor, or the like, or any combinationthereof. In some embodiments, the piece of photographic equipment or aportion thereof may be installed or disposed at a position closed to aradiation source of the medical imaging device. For example, the pieceof photographic equipment may be installed inside the medical imagingdevice and/or configured as a component thereof. Optionally oradditionally, the piece of photographic equipment or a portion thereofmay be installed at any other position. For example, the piece ofphotographic equipment may include two or more cameras installed insideand/or outside the medical imaging device, each of the two or morecameras may be used to acquire a 2D image of the target scan object, andtwo or more 2D images may be combined to generate 3D image(s) of thetarget scan object. In some embodiments, the optical image may beacquired during a scanning process of the target scan object.

The optical image may be generated, stored, or presented in a form of animage, a video frame, a video, etc. For example, if the scanning processtakes a relatively short time, the optical image may be an image (e.g.,an image may be generated by the piece of photographic equipment duringthe scanning process); if the scanning process takes a relatively longtime, the optical image may be a video (e.g., a video may be generatedby the piece of photographic equipment during the scanning process). Asanother example, if the scanning image is a 2D image, the correspondingoptical image may be a video frame; if the scanning image is a 3D image,the corresponding optical image may be a video.

Taking a CT scanning process as an example, the CT scanning process maytake a relatively long time in which scan data of the target scan objectmay be acquired, and accordingly, the piece of photographic equipmentmay acquire a video of the target scan object during the CT scanningprocess. Further, a 2D tomographic image corresponding to a specifictime point of the CT scanning process may be obtained by performing animage reconstruction process on at least part of the scan data, and the2D tomographic image may be associated with (or correspond to) a videoframe at the specific time point in the video. In such cases, the 2Dtomographic image may be determined as the scanning image, and the videoframe may be determined as the optical image. Alternatively oradditionally, a 3D image (and/or a plurality of 2D tomographic imagescorresponding to a plurality of (e.g., each) time point of the CTscanning process) may be obtained based on the scan data. In such cases,the 3D image may be determined as the scanning image, and the video maybe determined as the optical image.

In some embodiments, the optical image and the scanning image may beacquired simultaneously. For example, signals and/or instructions may besent to the medical imaging device and the piece of photographicequipment (e.g., at the same time) to cause the medical imaging deviceand the piece of photographic equipment to work simultaneously. In suchcases, the optical image and the scanning image may be acquiredsimultaneously. Optionally or additionally, the optical image may beacquired with a delay (e.g., a delay of milliseconds, a delay of tens ofmilliseconds, a delay of hundreds of milliseconds, etc.), andaccordingly, the optical image may correspond to the scanning image withan allowable time error. In some embodiments, the optical image and/orthe scanning image may include timestamp information or may beassociated with the timestamp information. In such cases, the opticalimage may correspond to the scanning image based partially on thetimestamp information, and accordingly, the optical image may be storedand/or displayed correspondingly with the scanning image. In someembodiments, a shooting angle of the optical image may be the same as orsimilar to a scanning angle of the scanning image, so that a perspectiveof the optical image may be the same as or similar to a perspective ofthe scanning image. In some embodiments, a shooting region of theoptical image may be the same as or similar to a scanning region of thescanning image. In some embodiments, the shooting region of the opticalimage may include and/or be larger than the scanning region of thescanning image, so that the optical image may at least include surfaceinformation of the scanning region of the scanning image. In someembodiments, the positions at which the piece of photographic equipmentare mounted may be designed and/or adjusted according to the shootingangle and/or the shooting region of the scanning image. For example, thepiece of photographic equipment may be mounted at a position close to oradjacent to a radiation source of the medical imaging device such thatthe shooing angle and/or the shooting region of the optical image mayinclude, or be the same as or similar to the shooing angle and/or thescanning region of the scanning image. As another example, scanningparameters (e.g., a scanning angle) of the scanning image may bepredetermined, and the piece of photographic equipment may be adjustedto a corresponding position such that the piece of photographicequipment may acquire the optical image from a same or similar shootingangle as the scanning image. In some embodiments, the scanning image mayinclude scan data of the target scan object acquired from a plurality ofscanning angles, and the optical image may be a video related to surfaceinformation acquired from a plurality of shooting angles. Taking a CTscanning process as an example, an X-ray tube and a detector may rotatearound a target scan object for acquiring scan data (e.g., 3D volumedata) of the target scan object from a plurality of scanning angles, andaccordingly, a piece of photographic equipment may rotate around thetarget scan object for acquiring a video including surface informationof the target scan object during the CT scanning process.

In some embodiments, the scanning image may be used to express internalinformation of the target scan object, such as morphology, a structure,a density and/or a function of internal tissues and organs of a humanbody. The optical image may be used to express surface information ofthe target scan object, such as a surface status, a posture, anocclusion or shelter on the human body. In some embodiments, the opticalimage may be acquired during a scanning process of the target scanobject in which the scanning image is acquired, so that surfaceinformation of the target scan object during scanning may be obtainedbased on the optical image, and/or may be used for or facilitate furtherprocessing or analysis of the scanning image (e.g., diagnosis ofdisease, treatment, image quality assessment, or the like, or acombination thereof).

In some embodiments, the optical image may include scan progressinformation of the target scan object. As used herein, the scan progressinformation may refer to information related to and/or parameters usedin a scanning process, such as a scanning time, a scanning angle, ascanning range, a scanning path, a scanning distance, or the like, orany combination thereof. In some embodiments, the optical image mayinclude scan status information of the target scan object. As usedherein, the scan status information may refer to information associatedwith a status of the target scan object when the scanning image isacquired. In some embodiments, the scan status information may include ashooting angle of the optical image, a shooting region of the opticalimage, a posture of the target scan object, a position of the targetscan object, a shelter of the target scan object (e.g., a shelter thatcovers a portion of the target scan object or the shooting regionthereof), a respiration phase of the target scan object, a cardiac phaseof the target scan object, or the like, or any combination thereof.

In some embodiments, the scan status information or a portion thereofmay be obtained based on the optical image. For example, at least partof the scan status information may be obtained by analyzing the opticalimage. As another example, the shooting region of the optical image maybe obtained based on a mark (e.g., a cross mark, a highlighted mark,etc.) projected on the target scan object when acquiring the opticalimage. In some embodiments, the mark may be generated by a projectiondevice installed into (or disposed at a position closed to) the piece ofphotographic equipment and may be further projected in the shootingregion. As a further example, the posture of the target scan object maybe obtained by performing an image recognition process (e.g., based onan image recognition algorithm, an image recognition model, etc.) on theoptical image. As still a further example, whether there is a shelter onthe target scan object may be determined or the shelter of the targetscan object may be identified by performing an image recognition processon the optical image.

In some embodiments, the scan status information or a portion thereofmay be obtained by using an external device. For example, therespiration phase and/or the cardiac phase of the target scan object maybe obtained by using external device(s). Exemplary external devices mayinclude a sensor (e.g., a pressure detecting sensor (e.g., an elasticbreathing band or a respiratory pressure pad configured to obtain arespiration motion curve of the target scan object)), an electrode(e.g., an electrocardiogram (ECG) electrode configured to obtain acardiac motion curve of the target scan object), or the like (e.g., apulse detecting clip, and/or a finger sleeve configured to obtain acardiac motion curve of the target scan object), or a combinationthereof.

In some embodiments, the scan status information or a portion thereofmay be obtained based on the scanning parameters (e.g., a scanningangle, a scanning range, a scanning path, a scanning distance, etc.)used in acquiring the corresponding scanning image. For example, becausea shooting angle of the optical image acquired by the piece ofphotographic equipment may be adjusted according to a scanning angle ofthe scanning image acquired by the medical imaging device, the shootingangle of the optical image may be obtained based on the scanning angleof the scanning image. As another example, the position of the targetscan object may be obtained based on hardware information (e.g., acoordinate and/or an angle associated with a gantry, a table, an X-raytube, etc.) of the medical imaging device.

In some embodiments, the scan status information or a portion thereofmay be shown in the optical image directly. In some embodiments, thescan status information or a portion thereof may be presented in anyother form (e.g., in a form of text, in a form of curve, in a form of amark, in a form of brightness variation (see FIGS. 5A or 6A), etc.). Insome embodiments, the scan status information of the target scan objectmay be used for or facilitate further processing or analysis of thescanning image (e.g., diagnosis of disease, treatment, image qualityassessment, or the like, or a combination thereof). For example, ifthere are artifacts in the scanning image, a user may check the opticalimage and determine whether there is an occlusion or shelter on thetarget scan object during the scanning process, or whether there is alesion (e.g., injury) in the target scan object.

FIG. 5A illustrates an optical image of a back region of an object(e.g., an animal). FIG. 5B illustrates a scanning image (e.g., a DRimage) of the back region of the object corresponding to the opticalimage shown in FIG. 5A. FIG. 5A and FIG. 5B may be acquiredsimultaneously, and the shooting angle of the optical image shown inFIG. 5A may be the same as or similar to the scanning angle of thescanning image shown in FIG. 5B. The object in FIGS. 5A and 5B may be ina same posture. FIG. 6A illustrates an optical image of a chest regionof an object (e.g., a human body). FIG. 6B illustrates a scanning image(e.g., a DR image) of the chest region of the object corresponding tothe optical image shown in FIG. 6A. FIG. 6A and FIG. 6B may be acquiredsimultaneously, and the shooting angle of the optical image shown inFIG. 6A may be the same as or similar to the scanning angle of thescanning image shown in FIG. 6B. The object in FIGS. 6A and 6B may be ina same posture. As shown in FIG. 5A (and/or FIG. 6A), a relativelybright region (e.g., the region A in FIG. 5A (or the region B in FIG.6A)) may correspond to a scanning region of the scanned object in FIG.5B (or FIG. 6B). Accordingly, the relatively bright region in FIG. 5A(and/or FIG. 6A) may be used as reference information in viewing,processing, or analyzing the DR images shown in FIG. 5B (and/or FIG.6B). For example, whether an occlusion or shelter is present on thescanned object may be determined according to the relatively brightregion. As another example, a surface condition of the scanned objectmay be determined according to the relatively bright region. Therefore,in practical applications, an optical image and a scanning image of asame target scan object may be acquired simultaneously, so that a user(e.g., a doctor) may trace scan status information of the target scanobject accurately when analyzing the scanning image, thereby assistingor facilitating the user to analyze the scanning image effectively,efficiently, and/or accurately based on the optical image.

In 420, the optical image and/or the scan status information of thetarget scan object may be stored correspondingly with the scanningimage. In some embodiments, the processing device 140 (e.g., the storingmodule 820 illustrated in FIG. 8 ) may preform operation 420.

In some embodiments, the optical image may be stored correspondinglywith the scanning image. In some embodiments, the scan statusinformation may be stored correspondingly with the scanning image.Taking an optical image in JPEG format as an example, in an imagestorage process, the optical image in the JPEG format may be storedcorrespondingly with the scanning image. Optionally or additionally, theoptical image in the JPEG format may be analyzed and converted into dataor information in any other format (e.g., a model image, a flashanimation, text information, or the like, or any combination thereof).The converted data or information may represent the scan statusinformation or a portion thereof. In some embodiments, the converteddata or information may be stored correspondingly with the scanningimage.

In some embodiments, to store the optical image (and/or the scan statusinformation) correspondingly with the scanning image, the optical image(and/or the scan status information) of the target scan object may bestored in a same file (e.g., a Digital Imaging and Communications inMedicine (DICOM) standard format file) as the scanning image.

In some embodiments, to store the optical image (and/or the scan statusinformation) of the target scan object correspondingly with the scanningimage, the optical image (and/or the scan status information) of thetarget scan object may be converted to a same format as the scanningimage. Merely by way of example, after a scanning process using amedical imaging device, a file (e.g., a DICOM standard format file) thatstores data including a scanning image of a target scan object may begenerated. An optical image of the target scan object in a non-DICOMformat (e.g., a JPG format, a JPEG format, a BMP format, a GIF format, aPNG format, etc.) may be acquired by a piece of photographic equipmentsimultaneously with the scanning process. In such cases, the opticalimage may be converted into a same format (e.g., the DICOM format) asthe scanning image such that the optical image may be storedcorrespondingly with the scanning image. More descriptions regarding thestoring of the optical image and/or the scan status information of thetarget scan object correspondingly with the scanning image may be foundelsewhere in the present disclosure (e.g., FIG. 7 , FIG. 9 and thedescriptions thereof).

It should be noted that the above description of the process 400 ismerely provided for the purposes of illustration, and not intended tolimit the scope of the present disclosure. For persons having ordinaryskills in the art, multiple variations or modifications may be madeunder the teachings of the present disclosure. However, those variationsand modifications do not depart from the scope of the presentdisclosure. For example, although only one piece of photographicequipment is illustrated in process 400, it should be understood thatthere may be two or more pieces of photographic equipment configured toacquire optical images. Correspondingly, two or more optical images maybe acquired simultaneously with the scanning image in operation 410.

FIG. 7 is a flowchart illustrating another exemplary process for imagestorage according to some embodiments of the present disclosure. In someembodiments, at least part of process 700 may be performed by theprocessing device 140 (implemented in, for example, the computing device200 shown in FIG. 2 ). For example, the process 700 may be stored in astorage device (e.g., the storage device 150, the storage 220, thestorage 390) in the form of instructions (e.g., an application), andinvoked and/or executed by the processing device 140 (e.g., theprocessor 210 illustrated in FIG. 2 , the CPU 340 illustrated in FIG. 3, one or more modules or units illustrated in FIG. 8 ). The operationsof the illustrated process presented below are intended to beillustrative. In some embodiments, the process 700 may be accomplishedwith one or more additional operations not described, and/or without oneor more of the operations discussed. Additionally, the order in whichthe operations of the process 700 as illustrated in FIG. 7 and describedbelow is not intended to be limiting.

In 710, a scanning image (also referred to as “first image”) of a targetscan object (also referred to as “subject”) may be obtained, and/or anoptical image (also referred to as “second image”) of the target scanobject may be obtained (e.g., using a piece of photographic equipment)during a scanning process of the scanning image. In some embodiments,the processing device 140 (e.g., the obtaining module 810 illustrated inFIG. 8 ) may preform operation 710.

In some embodiments, as described in connection with FIG. 4 , thescanning image may include or refer to a medical image obtained based onan interaction between the target scan object (e.g., a human body) and amedium provided by a medical imaging device (also referred to as“scanning device”, e.g., the scanning device 111 illustrated in FIG. 1). The scanning image may be used to express internal information (e.g.,a structure and/or a density of internal tissues and organs of the humanbody) of the target scan object. In some embodiments, the optical imagemay be acquired using a piece of photographic equipment. In someembodiments, the optical image and the scanning image may be acquiredsimultaneously. In some embodiments, the optical image may include scanstatus information of the target scan object. More descriptions of thescan status information may be found elsewhere in the present disclosure(e.g., FIG. 4 and descriptions thereof).

In 720, the optical image and/or the scan status information of thetarget scan object may be stored correspondingly with the scanningimage. In some embodiments, the processing device 140 (e.g., the storingmodule 820 illustrated in FIG. 8 ) may preform operation 720.

In some embodiments, to store the optical image (and/or the scan statusinformation) of the target scan object correspondingly with the scanningimage, the optical image (and/or the scan status information) of thetarget scan object may be converted to a same format as the scanningimage. Specifically, in some embodiments, character stream data may beobtained by performing a serialization process on the optical image(and/or the scan status information) of the target scan object accordingto a predetermined format. As used herein, the serialization process ofthe optical image (and/or the scan status information) of the targetscan object may refer to a process of transforming information of theoptical image (and/or the scan status information) of the target scanobject into a stream of bytes that can be stored or transmitted tomemory, a database, and/or a file. In some embodiments, thepredetermined format may include a format (e.g., an original format) ofthe scanning image (e.g., the DICOM standard format). Exemplarycharacter stream data in the DICOM standard format may include preamblecharacters, prefix characters, and data element characters. Differentcharacters may be used to store different information. For example, thepreamble characters may store information enabling a multi-mediaapplication to randomly access data (e.g., an image) stored in a DICOMfile. As another example, the prefix characters may store informationused to recognize whether a current file is a DICOM File. As a furtherexample, the data element characters may store information related tothe optical image (and/or the scan status information) of the targetscan object.

Further, the character stream data may be stored correspondingly withthe scanning image. In some embodiments, the character stream data andthe scanning image may be stored in a same file. Specifically, in someembodiments, the scanning image may be stored in a storage file (alsoreferred to as “a first storage file”), and the character stream datamay be stored in a pre-created storage space (also referred to as “afirst storage space”) of the storage file. In such cases, the characterstream data may be stored correspondingly with the scanning image. Insome embodiments, the storage file may be a DICOM standard format file,and the pre-created storage space may be a private tag space of theDICOM standard format file. As used herein, the private tag space mayrefer to a space reserved by a user in the DICOM standard format filefor private use. In some embodiments, each of the data elementcharacters may include a tag space. The private tag space may be aspecific tag space (or a pre-defined tag space) included in the dataelement characters. In some embodiments, the character stream data begenerated and/or stored correspondingly with the scanning image inreal-time during the scanning process of the scanning image. In someembodiments, the character stream data be generated and/or storedcorrespondingly with the scanning image after the scanning process isfinished or terminated.

In some embodiments, the character stream data may be storedcorrespondingly with the scanning image based on path information of astorage file of the character stream data. Specifically, in someembodiments, the scanning image may be stored in a second storage file(e.g., a DICOM standard format file), and the character stream data maybe stored in a third storage file. The second storage file may include asecond storage space (e.g., a private tag space). The path informationof the third storage file may be stored in the second storage space ofthe second storage file. As used herein, the path information of thethird storage file may refer to a general form of the name of the thirdstorage file which specifies a unique location in a file system in whichthe third storage file is stored. For example, the path information ofthe third storage file may include folder line information that can betraversed when the third storage file is retrieved. In some embodiments,the path information of the third storage file may be stored in thesecond storage space of the second storage file so that the secondstorage file is associated with the third storage file. In such cases,the character stream data may be stored correspondingly with thescanning image based on the path information. In some embodiments, thescanning image may be in the DICOM standard format, and the pathinformation may be stored in a private tag space of the DICOM standardformat file. Optionally or additionally, the optical image (and/or thescan status information) of the target scan object may be directlystored (e.g., without being serialized to character stream data) in thethird storage file. In such cases, the optical image (and/or the scanstatus information) of the target scan object may be storedcorrespondingly with the scanning image based on the path informationdirectly.

In 730, the scanning image, the optical image and/or the scan statusinformation corresponding to the scanning image may be output accordingto a request of a user. In some embodiments, the processing device 140(e.g., the output module 830 illustrated in FIG. 8 ) may preformoperation 730. In some embodiments, in response to receiving, from auser, a request for viewing the scanning image of the target scanobject, the processing device 140 may output the scanning image, theoptical image and/or the scan status information corresponding to thescanning image to a display device for display.

In some embodiments, the request may be input by the user via acomputing device (e.g., the I/O 230 of the computing device 200) or amobile device (e.g., the I/O 350 of the mobile device 300). For example,the I/O 230 or the I/O 350 may include an input device such as akeyboard, a mouse, a touch screen, a microphone, a trackball, or thelike, or a combination thereof, and the user may input the request byusing the input device. In some embodiments, the request may be furtherprovided or transmitted to the processing device 140 and/or othercomponents of the image storage system 100 (e.g., via the network 120).In some embodiments, the display device may be an output device of theI/O 230 or the I/O 350.

In some embodiments, the scanning image may be stored in a storage file(e.g., the first storage file), and the character stream datacorresponding to the optical image (and/or the scan status information)may be stored in a (pre-created) storage space of the storage file. Inresponse to receiving the request for viewing the scanning image of thetarget scan object from the user, the scanning image may be obtained orread from the storage file. Further, target character stream data (alsoreferred to as data in a target character stream) may be obtained fromthe pre-created storage space of the storage file. The target characterstream data may refer to the character stream data of the optical image(and/or the scan status information) corresponding to the scanningimage. In some embodiments, the scanning image may be stored in a DICOMstandard format, and the target character stream data obtained from thepre-created storage space of the storage file of the scanning image mayalso be in the DICOM standard format. In some embodiments, the targetcharacter stream data in the DICOM standard format may not be displayeddirectly. In such cases, the target character stream data may beconverted into one or more other formats for display. For example, thetarget character stream data may be converted into an optical image ofan image format such as a JPG format, a JPEG format, a BMP format, a GIFformat, a PNG format, etc. As another example, the target characterstream data may be converted into scan status information such as amodel image, a flash animation, text information, or the like, or anycombination thereof. In some embodiments, the target character streammay be traversed, and a deserialization process may be performed on thetarget character stream data to generate the optical image (and/or thescan status information). The scanning image, the optical image and/orthe scan status information may be further output to the display devicefor display.

In some embodiments, as described in connection with operation 720, thecharacter stream data corresponding to the optical image (and/or thescan status information) may be stored correspondingly with the scanningimage based on path information. For example, the scanning image may bestored in a storage file (e.g., the second storage file), the characterstream data may be stored in a third storage file, and path informationof the third storage file may be stored in a storage space (e.g., asecond storage space) of the second storage file. In response toreceiving the request for viewing the scanning image of the target scanobject from the user, the scanning image may be obtained or read fromthe second storage file. Further, the path information of the thirdstorage file may be obtained from the second storage space of the secondstorage file, and the third storage file may be obtained based on thepath information. Correspondingly, the character stream datacorresponding to the optical image (and/or the scan status information)may be obtained from the third storage file. In some embodiments, theoptical image (and/or the scan status information) may be generatedbased on the character stream data. For example, a deserializationprocess may be performed on the character stream data to generate theoptical image (and/or the scan status information). In such cases, thescanning image, the optical and/or the scan status information may beoutput based on the request.

According to the image storage processes provided in the presentdisclosure, a scanning image of a target scan object may be obtained,and an optical image of the target scan object may be obtained by using,e.g., a piece of photographic equipment, during the scanning process ofthe scanning image. Character stream data may be obtained by performinga serialization process on the optical image according to apredetermined format. The character stream data may be storedcorrespondingly with the scanning image. In response to receiving, froma user, a request for viewing the scanning image, the scanning image andthe optical image corresponding to the scanning image may be output to adisplay device for display. According to the image storage processes,the optical image and/or the scan status information may be storedand/or displayed correspondingly with the scanning image. Therefore, theuser may trace back to the optical image and/or the scan statusinformation quickly when viewing the scanning image, thereby improvingthe effectiveness, efficiency, and/or accuracy in analyzing the scanningimage.

It should be noted that the above description of the process 700 ismerely provided for the purposes of illustration, and not intended tolimit the scope of the present disclosure. For persons having ordinaryskills in the art, multiple variations or modifications may be madeunder the teachings of the present disclosure.

The second storage filemay include a second storage space, and the storing unit 822 may storethe path information of the third storage file in the second storagespace, so that the second storage file is associated with the thirdstorage file. In such cases, the character stream data may be storedcorrespondingly with the scanning image based on the path information.

In some embodiments, the processing device 800 may include an outputmodule 830, an extraction module, and/or a deserialization module. Theoutput module 830 may be configured to output the scanning image, theoptical image (and/or the scan status information) corresponding to thescanning image to a display device for display, for example, in responseto receiving, from a user, a request for viewing the scanning image ofthe target scan object.

FIG. 9 is a flowchart illustrating an exemplary process for imagestorage according to some embodiments of the present disclosure. In someembodiments, at least part of process 900 may be performed by theprocessing device 140 (implemented in, for example, the computing device200 shown in FIG. 2 ). For example, the process 900 may be stored in astorage device (e.g., the storage device 150, the storage 220, thestorage 390) in the form of instructions (e.g., an application), andinvoked and/or executed by the processing device 140 (e.g., theprocessor 210 illustrated in FIG. 2 , the CPU 340 illustrated in FIG. 3, one or more modules or units illustrated in FIG. 8 ). The operationsof the illustrated process presented below are intended to beillustrative. In some embodiments, the process 900 may be accomplishedwith one or more additional operations not described, and/or without oneor more of the operations discussed. Additionally, the order in whichthe operations of the process 900 as illustrated in FIG. 9 and describedbelow is not intended to be limiting.

In 910, the processing device 140 (e.g., the obtaining module 810) mayobtain a first image (e.g., a scanning image) of a subject (alsoreferred to as a “target scan object”). In 920, the processing device140 (e.g., the obtaining module 810) may obtain a second image (e.g., anoptical image) of the subject.

As described in connection with operation 410, the subject may include apatient, a man-made object, etc. In some embodiments, the subject mayinclude a specific portion, organ, and/or tissue of a patient. Forexample, the subject may include a head, a brain, a neck, a body, ashoulder, an arm, a thorax, a cardiac, a stomach, a blood vessel, a softtissue, a knee, feet, or the like, or any combination thereof.

In some embodiments, the first image may be acquired by a scanningdevice, and the second image may be acquired by a capture device (e.g.,a piece of photographic equipment). For example, the first image may bea medical image acquired based on an interaction between the subject(e.g., a human body) and a medium provided by the scanning device (e.g.,the scanning device 111 illustrated in FIG. 1 ). The first image may beused to express internal information (e.g., a structure and/or a densityof internal tissues and organs of the human body) of the subject. Moredescriptions of the mediums and the scanning device may be foundelsewhere in the present disclosure (e.g., FIG. 4 and descriptionsthereof). In some embodiments, the optical image may be acquired byusing the capture device (e.g., the capture device 112 illustrated inFIG. 1 ). More descriptions of the capture device may be found elsewherein the present disclosure (e.g., FIG. 4 and descriptions thereof).

In some embodiments, the first image may be acquired by a firstcomponent of a scanning device, and the second image may be acquired bya second component of the scanning device. For example, the scanningdevice may include one or more scanners that are configured as the firstcomponent, and one or more pieces of photographic equipment may bedisposed inside the scanning device and used as the second component.

In some embodiments, the second image may include scan statusinformation of the subject. The scan status information may beassociated with a status of the subject when the first image isacquired. More descriptions of the scan status information and thedetermination of the scan status information may be found elsewhere inthe present disclosure (e.g., FIG. 4 and descriptions thereof).

In some embodiments, the first image may include a 2D image, and thesecond image may include a video frame. In some embodiments, the firstimage may include a 3D image, and the second image may include a video.Taking a CT scanning process as an example, scan data of the subject maybe acquired by a CT scanning device and a video of the subject may beacquired by a piece of photographic equipment during the CT scanningprocess. Further, a 2D tomographic image corresponding to a specifictime point of the CT scanning process may be obtained by performing animage reconstruction process on at least part of the scan data, and the2D tomographic image may be associated with (or correspond to) a videoframe at the specific time point in the video. In such cases, the 2Dtomographic image may be determined as the first image, and the videoframe may be determined as the second image. Optionally or additionally,a 3D image (and/or a plurality of 2D tomographic images corresponding toa plurality of (e.g., each) time point of the CT scanning process) maybe obtained based on the scan data. In such cases, the 3D image may bedetermined as the first image, and the video may be determined as thesecond image.

In some embodiments, the first image and the second image may beacquired simultaneously. For example, signals and/or instructions may besent to the scanning device (or the first component of the scanningdevice) and the piece of photographic equipment (or the second componentof the scanning device) (e.g., at the same time) to cause the scanningdevice and the piece of photographic equipment to work simultaneously.

In some embodiments, the processing device 140 may obtain the firstimage from the scanning device (or the first component of the scanningdevice) and obtain the second image from the piece of photographicequipment (or the second component of the scanning device), directly. Insome embodiments, the first image and the second image acquiredsimultaneously may be stored in a storage device (e.g., the storagedevice 150) disclosed elsewhere in the present disclosure. Theprocessing device 140 may obtain the first image and/or the second imagefrom the storage device.

In 930, the processing device 140 (e.g., the storing module 820) maystore the second image correspondingly with the first image. In someembodiments, to store the second image correspondingly with the firstimage, the processing device 140 may store the second image and thefirst image in a same file.

In some embodiments, the processing device 140 may obtain characterstream data corresponding to the second image based on the second image.Specifically, in some embodiments, the processing device 140 may obtainthe character stream data by performing a serialization process on thesecond image. More descriptions of the serialization process may befound elsewhere in the present disclosure (e.g., FIG. 4 , FIG. 7 , anddescriptions thereof). In some embodiments, the processing device 140may perform the serialization process on the second image according to apredetermined format (e.g., a DICOM standard format).

Further, in some embodiments, the processing device 140 may store thecharacter stream data correspondingly with the first image.Specifically, in some embodiments, the processing device 140 may storethe first image in a first storage file (e.g., a DICOM standard formatfile). In some embodiments, the first storage file may include a firststorage space (e.g., a private tag space of the DICOM standard formatfile). The processing device 140 may further store the character streamdata in the first storage space of the first storage file. In suchcases, the character stream data may be stored correspondingly with thefirst image.

In some embodiments, to store the character stream data correspondinglywith the first image, the processing device 140 may store the firstimage in a second storage file. The second storage file may include asecond storage space. Further, in some embodiments, the processingdevice 140 may store the character stream data in a third storage file.In some embodiments, the processing device 140 may store pathinformation of the third storage file in the second storage space of thesecond storage file. More descriptions of the path information may befound elsewhere in the present disclosure (e.g., FIG. 7 and descriptionsthereof). In such cases, the character stream data may be storedcorrespondingly with the first image based on path information.

In some embodiments, the processing device 140 may also store the scanstatus information correspondingly with the first image. For example,the processing device 140 may determine the scan status information byanalyzing the second image. Further, the processing device 140 mayobtain character stream data by performing a serialization process onthe scan status information. Furthermore, the processing device 140 maystore the scan status information correspondingly with the first imagein a similar way as storing the second image correspondingly with thefirst image. More description regarding the storing of the second imagecorrespondingly with the first image may be found elsewhere in thepresent disclosure (e.g., FIG. 7 and the descriptions thereof).

It should be noted that the above description of the process 900 ismerely provided for the purposes of illustration, and not intended tolimit the scope of the present disclosure. For persons having ordinaryskills in the art, multiple variations or modifications may be madeunder the teachings of the present disclosure. However, those variationsand modifications do not depart from the scope of the presentdisclosure. According to the image storage method illustrated in theprocess 900, the first image may be stored and/or displayedcorrespondingly with the second image. A user (e.g., a doctor) may tracescan status information of the subject accurately when analyzing thescanning image, thereby assisting or facilitating the user to analyzethe scanning image effectively, efficiently, and/or accurately based onthe optical image. Moreover, redundant information generated during astorage process may be reduced by storing the first imagecorrespondingly with the second image, thereby saving storage space andimproving efficiency of image storage and/or image display.

FIG. 10 is a flowchart illustrating an exemplary process for outputtingan image according to some embodiments of the present disclosure. Insome embodiments, at least part of process 1000 may be performed by theprocessing device 140 (implemented in, for example, the computing device200 shown in FIG. 2 ).

The operationsof the illustrated process presented below are intended to beillustrative. In some embodiments, the process 1000 may be accomplishedwith one or more additional operations not described, and/or without oneor more of the operations discussed. Additionally, the order in whichthe operations of the process 1000 as illustrated in FIG. 10 anddescribed below is not intended to be limiting.

In 1010, the processing device 140 may receive a request for viewing thefirst image from a user.

In some embodiments, the request may be input by the user via acomputing device (e.g., the I/O 230 of the computing device 200) or amobile device (e.g., the I/O 350 of the mobile device 300). For example,the I/O 230 or the I/O 350 may include an input device such as akeyboard, a mouse, a touch screen, a microphone, a trackball, or thelike, or a combination thereof, and the user may input the request byusing the input device. In some embodiments, the request may be furtherprovided or transmitted to the processing device 140 and/or othercomponents of the image storage system 100 (e.g., via the network 120).

In 1020, the processing device 140 may output the first image and thesecond image for display based on the request.

In some embodiments, as described in connection with operation 930, thefirst image may be stored in a first storage file and character streamdata corresponding to the second image may be stored in a first storagespace of the first storage file. In such cases, the processing device140 may obtain the first image from the first storage file and obtainthe character stream data corresponding to the second image from thefirst storage space of the first storage file. Further, the processingdevice 140 may generate the second image based on the character streamdata. For example, the processing device 140 may generate the secondimage by performing a deserialization process on the character streamdata. Furthermore, the processing device 140 may output the first imageand the second image based on the request.

In some embodiments, as described in connection with operation 930, thefirst image may be stored in a second storage file the character streamdata corresponding to the second image may be stored in a third storagefile, and path information of the third storage file may be stored in asecond storage space of the second storage file. In such cases, theprocessing device 140 may obtain the first image from the second storagefile, and obtain path information of the third storage file from thesecond storage space of the second storage file. Further, the processingdevice 140 may obtain the third storage file based on the pathinformation, and obtain the character stream data corresponding to thesecond image from the third storage file. Furthermore, the processingdevice 140 may generate the second image based on the character streamdata. For example, the processing device 140 may generate the secondimage by performing a deserialization process on the character streamdata. In some embodiments, the processing device 140 may output thefirst image and the second image based on the request.

In some embodiments, the processing device 140 may also output the scanstatus information for display based on the request in a similar way asoutputting the first image and the second image for display. Moredescription regarding outputting the first image and the second image(or the scan status information) for display may be found elsewhere inthe present disclosure (e.g., FIG. 7 and the descriptions thereof).

It should be noted that the above description of the process 1000 ismerely provided for the purposes of illustration, and not intended tolimit the scope of the present disclosure. For persons having ordinaryskills in the art, multiple variations or modifications may be madeunder the teachings of the present disclosure. However, those variationsand modifications do not depart from the scope of the presentdisclosure.

In some embodiments, the present disclosure may also provide a computerreadable storage medium storing a computer program. When the computerprogram is executed by a processor (e.g., the processing device 140), animage storage method provided in the present disclosure may beimplemented. The method may include obtaining a scanning image of atarget scan object, and obtaining an optical image of the target scanobject acquired by using a piece of photographic equipment during thescanning process of the scanning image.
